Impact Socket Accessory Proline ZR18321, Length 28 mm

The Proline ZR18321 impact socket accessory, 28 mm length, is an adapter designed for use with impact wrenches and electric or pneumatic impact drivers. Manufactured from forged chromium-vanadium steel with precise hardening and tempering, the accessory has a chrome-plated and polished finish and is intended to provide secure transfer of torque between drive tools and sockets. The design includes specially profiled edges between working planes to reduce point loads and protect fastener heads and socket surfaces during heavy-duty use.

Advantages

The Proline impact socket accessory meets or exceeds durability requirements outlined by applicable standards through a heat-treated chromium-vanadium construction, ensuring consistent hardness and resistance to wear. Chrome plating adds corrosion resistance and a smooth surface for easy cleaning. The PRO-DRIVE profiling reduces the risk of fastener rounding and extends both socket and fastener life by distributing load more evenly across contact surfaces. Its compact 28 mm length allows use in confined spaces while maintaining impact-rated strength.

Suitable for

• Automotive repair and tire service where impact-rated adapters are required
• Machinery maintenance and industrial assembly tasks
• General workshop use with pneumatic or electric impact drivers
• Situations requiring work in tight or recessed spaces

Key specifications

• Material: forged chromium-vanadium steel with heat treatment
• Finish: chrome-plated and polished
• Length: 28 mm
• Design feature: PRO-DRIVE profiled edges to reduce point loads
• Intended use: impact-rated connector/adapter for sockets and impact tools

How to use

Select an adapter size that matches the drive and socket required for the fastener. Securely attach the Proline ZR18321 to the output square of an impact wrench or driver, then connect the appropriate socket to the adapter. Operate the impact tool according to the tool manufacturer's instructions, applying intermittent operation if required by the task. After use, inspect contact surfaces for wear and clean the chrome finish to remove debris and protect against corrosion.

Usage recommendations

Use only with tools and sockets rated for impact service. Avoid using cheater bars or exceeding the recommended torque of the socket system. Store the adapter in a dry place and inspect regularly for signs of cracking, deformation, or excessive wear before use.
